CYLINDER-COCK.

Specification of Letters Patent.

Patented Jan. 18, 19116.

Application filed September 17, 1915. Serial No. 51,189,

To all whom it may concern:

Be it known that we, HARRY J. BURKLEY and CrmRLns E. BURKLEY, citizens of the United States of America, and residents of Cameron, county of Marshall and State of lVest Virginia, have invented certain new and useful Improvements in Cylinder- Cocks, of which the following is a specification.

This invention relates broadly to valves, and more specifically to a cylinder cock or drain faucet for engine cylinders.

The primary object of the invention is to provide a drain cock for the cylinders of locomotives and other engines, wherein there are no parts liable to become broken and no parts subject to such wear as to permit leakage except after long-continued use.

As is well known, much trouble is experienced in keeping in perfect working order cylinder cocks of'the type commonly used on locomotives, due not only to the fact that the valve and its seat quickly become so worn that leakage occurs, but also to the fact that the valve stem which is formed integral with the valve frequently becomes broken off through sudden strains imposed thereon in withdrawing the operating lever to allow the valve to seat. Oftentimes when 4 said stem is so broken, the valve rises and turns over on its side, in which position all efforts to effect the seating thereof are fruitless.

It is the purpose of the present invention to obviate the objections named by the provision of a valve of simple and durable construction.

The invention resides in the features of construction, arrangement of parts and coin binations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a side elevation of the invention; Fig. 2 is a longitudinal section on the line 22, Fig. 1; and Fig. 3 is a transverse section on the line 33, Fig. 2

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views1 and 2 re= spectively indicate the upper and lower separable sections of a valve casing or cook body, said upper section 1 having its lower end interiorly threaded and having received therein the upper exteriorly threaded end of said lower section 2. A. valve chamber 3 is provided in the section 1 above the end of the section 2, and said chamber is adapted to have communication through a vertical passage at provided in the exterior-1y threaded neck of said section 1 with the interior of a cylinder into which said neck is threaded in the usual manner.

A valve seat 5 is formed in the upper end of the lower section 2 of the casing, the same normally having seated thereon a ball valve 6 which is operable within said chamber 3.

A vertically'disposed socket 7 of limited length is provided in the upper part of the lower section 2, the same communicating adjacent to its lower end with the atmosphere through a laterally directed port 8, and also communicating at its upper end with the chamber 3 when the ball valve 6 is unseated. Located within said socket 7 is a vertically movable plunger 9 having a vertically disposed stem 10 at its lower end, said stem operating in a guide passage 11 and protrading through the latter into a transverse guideway 12 formed in said lower sec: tion 2. The plunger 9 has longitudinal flutes 18 formed therein which afford passageways through which, when the valve is unseated, water may drain in a practically unobstructed manner to the port 8.

Projected through the guideway 12 and having horizontal movement therein is a bar or lever 14: of forwardly tapered form which has a downturned lug 15 formed on its front end. Said lever is operable from the cab of the locomotive or from other convenient position. In the normal or retracted position of said lever the lug 15 lies in engagement with the outer wall of the lower casing section 2 below the guideway 12, as shown in full lines in F ig. 2, said lug serving to prevent withdrawal of said lever from said guideway. The lower end of the stem 10 of the plunger overlies the upper edge of the lever 14, permitting said plunger to normally occupy a lowered position wherein it is removed from contact with the ball valve 6. hen said lever is thrust forward, said stem, riding over the inclined upper edge thereof, is elevated to substantially the position indicated in dotted lines in Fig. 2, effecting the unseating of the valve for permitting condensation products to drain from the cylinder.

It will be noted that the plug 15 carried by the lever 1a is turned downward, or in a direction opposite that of the lug of the common type of operating lever heretofore "alve chamber therein adapted to be in open communication with the interior of a cylinder, said lower section having a vertical socket in its upper end and having a port opening late ally outward from said socket adjacent to the lower end of the latter, a valve seat formed at the upper end of said socket, a ball valve within said valve chamber and normally disposed on said seat, a vertically movable plunger located in said socket and adapted to permit the passage of water thereby, said lower section having a transverse guideway therethrough and having a vertical passage leading from said socket into said guideway, a stem carried by said plunger and protruding into said guideway through said passage, and a tapered lever extending through said guideway in engagement with saidstem and adapted for movement to effect the elevation of the plunger into unseating relation to said valve, said lever having a downwardly extending lug on its lower end.

Copies of this patent may be obtained for 2. Drain mechanism for engine cylinders, v.

comprising upper and lower separable casing sections, the upper section having a valve chamber therein adapted to be in open communication with the'interior of a cylinder, said lower section having a vertical socket in its upper end and having a port opening laterally outward from said socket adjacent to the lower end of the latter, a valve seat formed at the upper end of said socket, a ball valve within said valve chamber and normally disposed on said seat, a vertically movable plunger located in said socket and adapted to permit the passage of water thereby, said lower section having a transverse guideway therethrough and having a vertical passage leading from said socket into said guideway, a stem carried by said plunger and protruding into said guideway through said passage, and a lever extending through said guideway having its upper edge in sliding engagement with said stem, said lever being adapted for movement to efiect the elevation of the plunger into unseating relation to said valve, said lever being provided with a downward lug adapted to engage the casing for preventing its withdrawal from said guideway, the vertical thickness of the free end of said lever, including said lug, being less than the vertical height of said guideway.

In testimony whereof we affix our signatures in presence of two witnesses.
